Habit: Not getting enough antioxidants

Habit: Not getting enough antioxidants

If you aren't chowing down on at least five servings of fresh fruits and veggies a day, you're probably low on antioxidants. That means "you're not getting that necessary protection from free radicals, which speed the breakdown of collagen in our skin cells to cause wrinkles and sagging," says Nicola Bannon, head beauty therapist at NYR Organic Beauty Spa in London.

The most important antioxidants for skin health are A, C, and E. Find a great cream that includes all three, and stop wrinkle-causing free radicals in their tracks. Alternatively, take supplements as some research shows antioxidants may be most useful when taken internally. (Popping them daily could score you younger-looking skin in as little as six months). Can't remember to take your vitamins? "Green tea is one of the best sources of antioxidants, and it also acts as an anti-inflammatory," says Bannon.
